Description for the calculation of rectangles
A rectangle is a simple geometric shape and has the following characteristics
It has four sides and four corners
All corners are rectangular
The opposite sides are parallel and have the same length
Both diagonals are the same length
\(a = A / b\)
\(b = A / a\)
\(A = a ·b\)
\(P = (2 · a) + (2 · b)\)
\(d = \sqrt{a^2 + b^2}\)
